Shark clean and empty vacuum
I am enjoying this vacuum it is lightweight , the head is flexible and the fact that it will pick up dirt when moving forward and backwards without leaving anything behind which is perfect. The self emptying is amazing saving time and allowing emptying less often. I recommend this product.
